What utter nonsense. Just because you poorly configured your system does
not mean that Red Hat never really mastered it... And translating very old
experiences to CentOS 7 is even more ridiculous and counter productive.
To the OP enumerate is always painful, I'd remove that for a start.
My experience with the DAV SVN though is that clients are horrible in their
requests... So many it hits it so hard...
After various testing I ended up going with the Apache LDAP cache module
and doing the auth at the Apache level, not system.
Was far better in performance with the SVN server being hit fairly hard. I
can try and dig out an example configuration if you would like.
The bonus here as well is that svn users are separated cleanly from system
users... No reason for a dev to have a shell account on there ;)
